Oss.—At page 227 of the “Bot. of Voy. Herald,” I 
described the Fern from which the above character is 
derived, under the name of Ctenopteris (Glyphotemium) 
crispata, and stated that I considered it allied to Polypodium 
scolopendroides, Hook. and Grev. and P. suspensum, Sw., 
but from which it differs in having anastomose venation, 
and its vernation being adherent, not articulate, as in these 
two mentioned species ; I therefore deem it best to charac- 
terise it as a distinct genus under the above name. These 
characters, and the peculiar habit of the plant, renders it 
difficult to point out its true affinity otherwise than in 
Ctenopteris. It grows ina pendulous manner on trees in 
Darien and Panama. 
Sp. G. crispatum, J. Sm. 
: Tribe 13.—PHEGOPTERIDEZE. (Plate 13). 
Fronds varying from simple to decompound multifid. 
Venation free or anastomosing in various ways.  Sori 
punctiform or linear, naked or furnished with an indusium, 
which is either lateral, peltate, rarely calyciform. 
Oss.— This is an extensive tribe of Ferns, comprehending 
all the Phegopteris section of Polypodium and the tribe 
Aspidiacee as given in the “ Species Filieum," the number ` 
. being, as reduced in the “ Synopsis," 366; while Mettenius, _ 
ina special memoir of Phegopteris and Aspidium, enumerates 
299*. In the greater number the vernation is fasciculate 
and acaulose, and in others uniserial With few exceptions 
* In the Appendix to Syn. Fil. sixty-oné species are enumerated, the 
greater number of which belong to this tribe. oe
